Dear Junior Admin,
PCs generally have an eight day default lease period. The PC will not make contact to the DCHP server again until halfway through the lease time. Since you changed the scope on Friday, the PCs that just renewed a lease will not contact the DCHP until Tuesday. You may force the PCs to grab new IP addresses by opening a DOS prompt, and do an “ipconfig/release” and an “ipconfig/renew” on each computer.
If the problem still isn’t solved, check your scope configuration, and make sure the network/subnet mask match what is configured on the router that is connected to this local LAN.

Dear Junior Admin,
Active Directory integrated zones must be hosted by Domain Controllers (DCs), and all Active Directory integrated zones are primary zones. Given this, we’re really talking about where to place Domain Controllers servicing the additional role of DNS server.
Determining where to place DCs/DNS servers isn’t always straight-forward. However, as a rule of thumb, I take the view that any branch location that’s going to be utilize Active Directory services (authentication, file services, etc.), benefits from having a local DC and domain-integrated DNS services.
You might already know much of this, so bear with me…
When deciding where to place DC/DNS Servers, keep the following things in mind: * Domain members rely heavily on DNS services to locate domain resources. For example, when a domain-joined computer boots, it queries domain Service Locator records (SRV) in DNS to locate a Domain Controller against which to authenticate. Without a local DNS instance, this process has to take place over a potentially slow site link. Of course, once a computer has located a Domain Controller, it will continue to authenticate against that server until it something forces the client to find another DC. * Over a slow link, the regular…...

DNS SCENARIO It is not required to put a DNS server in such a small location for only five users and snail like network connectivity doesn’t justify the amount of money it would cost to install a server(s) in that area. One exception would be if there is a great amount of file sharing, or other information that would need to be accessed daily by other spots on the network. This sometimes but rarely happens but we could have a situation where we put it in the in the server but we set it up as a secondary or Active Directory Integrated zone type. I recommend installing the servers in the location where you have 30 users and fast internet connection. You could do this also, try storing all the files from either location in the bigger office, and in the smaller location you could remote connect through Virtual Private Network. When we do this all the information from the smaller sight is stored off site. The sight with five users can be run with a cheap router and the server that has thirty users at the office will be set up as the primary zone; since this is utilizing the fast internet connection and has more users this is our MAIN BASE which you can call home. =) If you were to run Domain Name System on domain controllers there are Active Directory Integrated zones and Active Directory Integrated zones.

...Phil Bohrer, NT1330 Unit 2 homework. 4/02/12 Assignment 1: DHCP Troubleshooting. Check the workstations using ipconfig /all and find out if the ip range is within the address range you assigned, if it is a different address then the workstation failed to contact the DHCP server and has gone into apipa mode. The Network Interface Card might be assigned an incorrect driver. Another possible cause of the problem is that the patch cable is not plugged into the Network Interface Card, or is not connected to a switch on the other end. However, it could be that the server has run out of IP addresses that it can assign to clients. You can easily tell if this is the problem by comparing the size of the DHCP address scope to the number of devices on your network that request IP addresses from the DHCP server. But since only some of the workstations have got addresses the problem might be the DHCP server. Start off by doing some ping tests to verify that the DHCP server is able to communicate across the network. If the DHCP server is able to communicate with other computers on the network, then I recommend verifying that the DHCP server has an IP address that is compatible with the scope that the server is configured to assign addresses from. The server itself has to be assigned a static address in the same subnet range, such as If this still doesn’t solve the problem make sure that the DHCP server is still authorized by the Active Directory to lease IP addresses.

Nt1330 Unit 1 Assignment 1

...Unit 1 Assignment 1 DNS servers provide domain name resolution for network resources. They associate the TCP/IP address assigned by DHCP to a client with its fully qualified domain name. The association of an IP address to a domain name requires that a change in either the address or the name requires an update of the information in DNS. The DHCP protocol does not do this automatically. To make this more seamless, servers running Windows Server® 2008 and DHCP and clients running DHCP can register with DNS, allowing the two to cooperate (TechNet) Dynamic Host Configuration Protocol (DHCP) is a protocol that assists in configuring IP addresses, subnet masks, default routers, and other IP parameters to client PCs that don't have a static IP address. These computers locate a DHCP server in their local network that gives them an IP address so they can connect to the internet or other computers within the local network. (dhcp server) There are four way to allocate dynamic IP addresses: automatic, dynamic, roaming, and manual. Three of these (dynamic, roaming, and manual) use DHCP to assign the IP addresses. (DHCP Servers) There are a number of downsides to administering IP addresses statically. Foremost is human error. If the administrator mistypes the IP address or subnet mask, the workstation may not have connectivity to the resources it requires. If the DNS or WINS server IP addresses are mistyped, the workstation will not be able to perform name resolution. If the default......

...NT1330-Unit 2 Exercise 1 DNS Scenario Dear junior IT, Thank you for contacting me regarding your questions, and trust that I will do my best to help you. From what I understand, you work at two branch offices, and have been given the responsibility of discovering where to place an Active-Directory Integrated DNS server. You also have some question of what type DNS server would best meet your company’s needs. First let’s begin with the smaller branch supporting perhaps five user/workstations, with an unusually slow network. The question with such a small branch isn’t really about what kind of DNS server you need, but do you need a DNS server at all. If there is a very high level of file/data sharing, then yes perhaps you could benefit from a server, but configured in a secondary zone, such as an ADI. However, if there is not enough file/data sharing to really warrant the presence of the server, an ADI server could potentially slow down an already sluggish system. Now let’s move on to the second, much larger branch supporting around thirty users. You stated that this branch has a much better network connectivity than its smaller counterpart. In this case, I would recommend a DNS server set up in the primary zone. The primary zone is the primary source of information within this zone. I would also further suggest moving your servers from the smaller branch to your larger branch. All files from the smaller branch could be accessed via a “VPN” remote link. This would......

...NT1330 Unit 4 Assignment 1. AD Design Replication Scenario AD Design Replication Scenario To whom it may concern: I am the IT Administrator for the company and I have been asked to give my recommendations for the Active Directory Replication Design of the two new Branches. The first I can recommend for you is that all the information that is needed for each new site is correctly documented and added to the Root Active Directory through the Active Directory sites and services. This is done because the Root AD automatically builds the inter-site replication topology based on the information provided about the new site connections. Each new site’s AD will have one each domain controller that is known as the inter-site topology generator and they are assigned to build the topology at their sites. To add two new branch offices we will need to find a strategy to design a replication process. To implement this we will need to use inter-site replication. Inter-site replication is needed when adding domain controllers located in different sites. We will also need a site link (Site link is a logical, transitive connection between two sites that allows replication to occur) protocol of Remote Procedure Call (RPC) over Internet Protocol (IP) which is the preferred choice for the replication process. This allows you to communicate with network services on various computers and also keep data secure when being transmitted by using both encryption and......

...NT1330 Client Server Networking II Mr. Pham Unit 2 Assignment 1 Dear Junior Admin, Regarding your task with changing out the DHCP You can start by checking the workstations and seeing if they have an static IP setup on the network adapter. There are 2 ways to check this. The first way is to click on the run command in the start menu and type cmd and hit enter. Next type in ipconfig /all, depending on how many Network Interface Card or NIC cards are installed (both logically and virtually.) you might get a long list . Look for your main NIC card that you are configuring. Once you find your NIC card that you are looking for, you should see a line that says DHCP Enabled. If there is no static IP address set up then it should say yes. The second way to check is to open the control panel. Find and open the Network and Sharing Center. On the right hand side you should see an option for change adapter settings. Select you main NIC card and right click and select properties. Select and double click on Internet Protocol Version 4 (IPv4). Once the window pops up, make sure that both the radio buttons for obtain IP Address automatically are selected. You should also check to see if each workstation has renewed its DHCP lease. To do this you can repeat the steps in the first way to change the DHCP setup. Once again you want to look for your main NIC card that you are configuring. Once you find your NIC card that you are configuring you should see 2 lines that say Lease......

I know how frustrating this can be especially when you feel like you have done everything right only to have the network get the better of you. A DHCP scope only determines which IP address is allocated to the clients. A scope defines the set of IP address and associated configuration information that can be supplied to a DHCP client. As you are aware a scope must be defined and activated before a DHCP client can use the DHCP server for dynamic TCP/IP configuration. You are more than able to configure as many scopes on a DHCP server as you need on your network environment. You are aware that as a DHCP administrator you can create one or more scopes especially on one or more Windows Server 2008 which is running the DHCP server service...

Nt1330 Unit 1 Exercise 1

...IP Addressing Scenario Unit 1 Exercise 1 ITT Technical Institute Floyd Washington Jr. April 4, 2015 When setting up a network that will consist of many host computers, one of the first things that an administrator must do is to determine what class of networks that they must administer to a given business. This is the point where every administrator must know how to implement classful and classless IP addressing. A classful network is a network addressing architecture used in the internet from 1981 until the introduction of Classless Inter-Domain Routing (CIDR) in 1993. Classful IP addressing divides the addtess space on the internet into five address classes. Each class is coded in the first four bits of the address. Today the classful network concepts remain in play only limited scope of the default configuration parameters. There are 32 bits contained in any IPv4 IP address. A Class A network has eight bits in the network number field and 24 bits in the rest of the field and covers a range of 0-126 in the leading field. There are 128 Class A networks with 16,777,216 hosts capability per network. The range of the Class A networks are to A Class B network has 16 bits in the network number field and has 16 bits in the rest of the fields and covers a range from to There are 16,385 Class B networks and each network has the capability of having 65,536 network hosts.

...Group Policy in a Mixed Client OS Environment Unit 8 Assignment 1 ITT Technical Institute Floyd Washington Jr. May 16, 2015 Group policy is a tool used for customizing, controlling, and securing Windows operating systems. It was introduced in Windows 2000 as part of the IntelliMirror technologies. Group policy can be applied at the local computer level or to OU’s, domains, or sites in an Active Directory environment. Group policy was supported by Windows XP Professional, but not XP Home Editions. Group Policy in Vista adds many settings which gives administrators more control over users and computers. In this essay I will discuss five of the newer features that was not in the older versions of windows. * The first policy that I will discuss is the Control Removable Media policy. Devices like thumb drives, flash memory card readers, and external USB hard disks made it easy for users to transfer data between two computers. Although convenient, the ease that removable media created brought about the rise in industry espionage. User could easily copy and share company secrets with competitors by copying the information on to a removable device and uploading it to another computer. Software was made available to block access to USB ports on sensitive terminals. * The second policy that I will discuss is the Control power management settings. Power management on a single computer can save energy and money. Enforcing a power management strategy can save a......

Nt1330 Unit 1 Assignment 1

...NT1330 Mr. Ajero Assignment 1 September 14, 2015 DNS – Domain Name System DNS is a hierarchical representation of all the IT devices and their sub-domains in a (company) network. So, in case you see an address like mail.subdomain.company.com, you can easily recognize the name of the system (mail), name of the sub-domain (sub-domain), name of the company (company) and the name of the primary domain (.com). DHCP – Dynamic Host Control Protocol A DHCP server automatically assigns the IP addresses for a device. Any device, before communicating with any other device in the network needs an IP address. These IP addresses are given to the network devices dynamically by a DHCP server (IP addresses ought to be within a certain range and the range is already specified). The IP addresses assigned this way are not permanent – they are actually leased for a certain amount of time to the devices (till they log-out of the network, for example). I believe that two hosts should be sufficient. Using a DHCP Relay Agent would greatly reduce the time necessary for me to set up the name allocation and resolution. If I were to do this manually on a static IP Address, I would have to put a stop to it at 25 machines as it would waste valuable time with trying to get to the other pieces of equipment my client owns. Regardless of if I was getting paid by the hour, I would need extra time for future maintenance and upgrades References DNS and DCHP......

Nt1330 Unit 2 Exercise

...Unit 2 Exercise 1 DNS Scenario Hello, I have received your email, and will do my best to help you out with the tasks put before you. First, let me say that a good rule of thumb to go by for DNS as far as users, and computers is if you have 10 or more. Seeing that you have 5 it is not a must have, but if your company has the money allocated for this project than go ahead. They might have growth in mind for the near future. If that is the case then the zone you would want the 5 employees in would be secondary if not possibly try setting up a VPN virtual private network to a server at the larger office. As far as the branch office with about 30 users I would definitely use a DNS server. You would put this branch in the primary zone. Another zone or setting that could be used is Active Directory Integrate Zone. The Active Directory Integrated zone stores its data in Active Directory and it does not need DNS zone files. It is in fact an authoritative primary zone and the data gets replicated to other domain controllers as part of Active Directory’s replication process, and a benefit of this type of zone is that it uses the security features of Active Directory. Active Directory will automatically replicate DNS information to other DNS servers that are installed on Active Directory Domain Controllers. I do hope that the information I provided was helpful, and if you have any further questions please feel free to contact me again....

...Unit 2 Assignment 1 DHCP troubleshooting Hello Junior Administrator, Let me clarify your parameters and intent… You have stated that you were tasked with changing the DHCP scope to match you IP addressing scheme. The IP address range you are using is through I have come up with a couple solutions and approaches to help you with your problem. First of all make sure you have typed all your numbers correctly. At times, a simple number incorrectly typed can throw the entire scheme off. Perform the same check for your subnet inputs as any slight number mistype will negate everything that you are trying to achieve. Make sure the scope is under the established DHCP local role IP address range on your assigned server. My next approach would be to see if there is connectivity between your user machines and the network. Make sure your network interface cards are all up to date and functioning. The other approach I will suggest can be involved if you’re not used to working with your command prompt however it’s doable with a detailed memo to your employees. I would have them release their IP addresses and renew them to through the console command input. I understand that most users may not have the required know how to do these tasks but for those I would actually go and input the commands manually and hopefully this will finally fix your problems.
